Ocean Influences Quiz Flashcards
Oceans play a major role in determining the climate by…
It’s ability to store & distribute heat energy through currents and winds
True or False, Earth’s climate and weather, is more important than the sun?
true
What is the greenhouse effect?
a term used to describe energy from a nearby star (in our case, the Sun) being trapped inside a planet’s atmosphere, thus warming the planet.
What does the insulating effect of water do?
Gives coastal areas a more moderate range of temperatures than inland areas with the same latitude do to water’s high heat capacity.
True or False, regions near the equator receive more heat than those near the poles?
True
How does a gyre start?
When surface currents driven by atmospheric winds move warm equatorial waters to the poles and cold polar waters to the equator setting up a nearly circular patterns of movement know as gyres.
What has the greatest influence on climate in open oceans and along edges of continents.
The Gulf Stream
What is the trend regarding linear speed and latitude?
As the latitude increased, the linear speed decreased.
How fast do you travel on the equator
1045mph or 1672kph
What are the directions objects deflect on each side of the hemisphere and what is this called?
Northern Hemisphere: clockwise
Southern Hemisphere: counterclockwise
This is called the coriolis effect
What relationship exists between the temperature of currents and the direction they flow.
Warm currents go to the poles while cool currents head toward the equator.
What determined trade routes and European imperialism and modern political geography.
Winds and currents
What is Linear Speed?
The speed an object moves which is determines by distance/time
